PENCIL-SHARPENER.

Specification of Letters Patent.

Patented April 24., 1906.

Application filed May 31,1905. Serial No. 262,996.

To all whom it may concern:

Be it known that I, PERRY GARST, residing at Portsmouth, New Hampshire, have invented certain new and useful Improvements in PencilSharpeners, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a machine of sim le construction which will rapidly and e' ciently sharpen and point pencils.

Certain forms of my invention are embodied in the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side elevation of one form of my machine, showing only one pencil-holder. Fig. 2 is rear'view of another form, showing a plurality of pencil-holders. Fig. 3 is still another form showing a plurality of grindingdrums and encil-holders. Fig. 4 is a front elevation of another embodiment of myinvent-ion. Fig. 5 is a plan view of the same.

The same reference characters indicate the same parts in the several views.

The part marked 1 represents the base of the machine. 2 and 3 are standards, and 4 and 5 frames secured to the base and inwhich the working parts of the apparatus are mounted.

6 is a shaft rotatably mounted in the standards and frame, and 7 is a crank or handle for rotatin the shaft.

8 is a coilar secured to the shaft, which has a pin or rod.9 projecting from one of the faces thereof.

10 is a drum frusto-conical in shape, which is loosely mounted on the shaft 6 and has a longitudinal sliding movement thereon.

11 is a hole through the hub of the drum, through which the rod 9 passes, the said rod being of such length that the drum may be movable longitudinally of the shaft a considerable distance without being disengaged from the rod. As the rod and the hole through which it passes are eccentric to the shaft 6, the drum will be'rotated by the rod upon the rotation of the shaft.

12 is a spiral spring surrounding the shaft 6, one end of which bears against the inner face of "re standard 2. and the other against the hub of the drum. The spring forces the drum toward the encil-holder and applies pressure to a penci being sharpened in a line ing-drum a with the axis thereof and automatically fee s and keeps the cutting drum to its work. The periphery of this drum may be covered with grinding or abrasing material 13, such as sandpaper, or the drum itself may be }nade of emery or steel having a cutting-sur- "ace.

14 is a gear-wheel secured to the shaft 6.

15 is the pencil-holder or chuck mounted in the frame 4 5.

16 is a pinion secured to the holder. 7

In the embodiment of my invention, as shown in Fig. 1, only one pencil-holder is illustrated; but it is apparent that a plurality of holders may be employed. 17 is an idle pinion secured to the end of the shaft or stud 18, mounted in the frame 4 5. U on turning the crank 7 motion is transmitte to the penoil holder or holders by the gears 14 and pinions 17 and'16, and rotary motion is transmitted to the grinding-drum by the rod 9.

With the pencil in the holder both the grind ing-drum and the pencil will be rotated upon rotating the shaft 6, and the end of the pencil will be ground down to give ita proper point. The spiral spring 12, actlng to press the grindainst the pencil in line with the axis 'thereo will more efliciently and accurately grind and oint the pencilthan if pressure were applie in any other direction.

In the form of machine shown in Fig. 2 the gear 14 meshes directly with the pinion 16 on the pencil-holder, and in this embodiment there is a series of holders, five in number, so that five pencils may be sharpened at the same time. I construct the frames 4 and 5 with radiating arms 19 to accommodate these different holders.

In the embodiment of my invention shown in Fig. 3 I provide a series of grinding-drums and mount each of these drums on a separate shaft 6, the frame being provided with the arms 19 in which the said shafts 6 are mounted, there being two pencil-holders, one

on each side of each of these grinding-drums.

Secured to the shafts 6 are the driving-pinions 20. These pinions, as well as the pinions 16, which drive the pencil-holder, mesh directly with the drivinggear 14. Upon rotating the driving-shaft 6 rotary motion is transmitted simultaneously to all of the pencil-holders and to the grinding-drum.

In the embodiment of my invention shown in Figs-4 and 5 I secureto the base 1 a frame consisting of the side piece 4", which has two arms 4 and 4 projecting at right angles 2 and the other in the arm 4* of the frame.

engagement with the driving-gear 14.

Secured to this shaft is the pinion 21, which meshes with the idler 22, said idler being }in T e grinding-drum is mounted on this shaft 6 In this case the rod 9 is secured directly to the shaft instead of to a collar secured to the ha The bevelof the grindin -drum may be varied so as to give different engths of points to the pencils, and my a paratus may be provided'with grindingr'ums havin different bevels for this lpur ose. By providing a plurality'of penci -ho ders not on] may a number of pencils be ground at t e same time, but" encils of different kinds and sizes may also e sharpened and pointed With long or short pointsduring the same operation.

I As many changes could be made in the above construction and many apparently 3o widely different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements'of the scope of the invention which as a matter of language might be I said to fall therebetween. I
